So I'm having a problem with the green on my projection TV. The red and the blue are totally fine. The green is OFTEN fine and working perfectly for random periods of time after the TV is turned on, but whether it's 5 minutes or 5 hours, the green will eventually warp (and it always warps exactly the same amount). I've read some other posts on this site concerning convergence problems with this TV, but none of them mentioned that their TV often works correctly, which makes me think I might have a lesser problem. Possibly I have a loose connection?
Possibly a loose connector or coolant leak, probably a solder joint on the conv. ic's, or resistors (3149-3160),or crt board. This condition will not improve by itself, continued use without repair can stress other parts and cause additional damage. You might get by just fixing the bad solder, many would advise replacing the ic's "while you are in there".
